Definitions

  • This invention relates to the field of multi-positionable brushes in general, and, in particular, to bi-positionable toothbrushes.
  • an angularly adjustable toothbrush may be constructed of two moldable parts and a pin.
  • the two parts are the rotatable brush head member and the handle.
  • the brush head member is elongated and rigid having a predetermined length, with a forward end and an after end, the forward end supports a brush array extending laterally, and the after end of said member being flared and terminating in an essentially flat first surface angled with respect to a long axis of the member.
  • This first angled surface includes a series of symmetrical locking features.
  • the brush head member has a first axial bore commencing at the first angled surface and is orthogonal thereto and terminates inwardly.
  • the axial bore including a means of removably and rotatably securing a pin therein.
  • the handle has a predetermined length, with a forward end and an after end, the forward end of the handle being flared and terminating in an essentially flat second angled surface angled with respect to a long axis of the handle.
  • the second angled surface includes a series of mating symmetrical locking features configured to mate with the symmetrical locking features of the first angled surface of the brush head member.
  • the handle has a second axial bore, which includes securing features, commencing at the second angled surface and orthogonal thereto and terminating inwardly.
  • the pin is of cylindrical cross-section and has a forward end and an after end and includes at the forward end, a means of being removably and rotatably secured within the first axial bore of the brush head member.
  • the pin includes at the after end, a means of being permanently secured within the second axial bore of the handle.
  • the handle of the angularly adjustable toothbrush include a series of finger gripping features. It is also preferred that the symmetrical locking features on the angled surface of brush head member and the angled surface of the handle are a series of parallel grooves. In an alternative configuration it is preferred that the symmetrical locking features on the angled surface of brush head member and the angled surface of the handle are a series of mating pins and holes.
  • the present invention may be constructed of two moldable parts and a bifurcated pin.
  • the brush head member is elongated and rigid, with its forward end carrying bristles extending transversely outwardly from one side of the forward end.
  • the after end of the brush head member terminates in an essentially flat surface angled at less than 90 degrees to the long axis of the member.
  • the after end of the brush head member contains an axial bore orthogonal to the angled flat surface.
  • the axial bore extends partially into the member and terminates in a transverse passage.
  • the axial bore is counterbored to approximately twice the diameter of the axial bore for approximately the first one forth of its depth from the angled flat surface.
  • the angled flat surface of the brush head member includes a series of symmetrical locking features such as parallel grooves, holes or projecting pins.
  • the handle is elongated and rigid and its forward end may include a series of finger grip features.
  • the forward end of the handle terminates in an essentially flat surface angled to the long axis of the handle at an angle complementary to the included angle between the angled surface of the brush head member and the long axis of the member, that is, such that the sum of the two angles is 180 degrees.
  • the angled flat surface of the handle contains a series of symmetrical locking features such as parallel grooves shaped to mate with the matching symmetrical locking features on the angled flat surface of the brush head member.
  • the forward end of the handle includes an axial bore, containing threads or some other securing feature, othoganal to the angled flat surface.
  • the bifurcated pin is formed of a resilient material and is cylindrical in cross-section.
  • the forward end of the bifurcated pin includes a split head which is of larger diameter than the axial bore in the brush head member but able to be compressed to the diameter of the axial bore due to the split in the head.
  • the split head expands to its full diameter when it passes into the transverse passage which terminates the axial bore in the brush head member.
  • the two halves of the split head are attached to the split portion of the shaft of the bifurcated pin extending backwardly from the head.
  • the diameter of the shaft is sized to slide easily within the axial bore of the brush head member.
  • the shaft of the bifurcated pin includes a non-split portion extending rearward from the split portion to provide additional strength to the shaft.
  • the bifurcated pin Extending rearward from the non-split portion of the shaft the bifurcated pin includes a portion of increased diameter shaped to fit the counter-bored portion of the axial bore in the brush head member.
  • the increased diameter portion also serves to add strength to the bifurcated pin.
  • Extending rearwardly from the increased diameter portion of the bifurcated pin is a portion of reduced diameter, including threads or other securing features, shaped to fit the mating securing features of the axial bore in the handle.
  • Selection of the angle of the brush head member with respect to the handle is effected by pulling the handle away from the brush head member sufficiently to retract the split head of the bifurcated pin from the transverse passage in the brush head member and into the smaller diameter of the axial bore.
  • the bifurcated pin is so retracted the mating symmetrical locking features on the angled flat surfaces of the brush head member and the handle will be disengaged and the handle may be twisted with respect to the brush head member.
  • the resulting toothbrush When the handle is twisted to a first position and the handle pushed into the brush head member so that the symmetrical locking features align, the resulting toothbrush will have an essentially straight handle.
  • the angled surfaces of the brush head member an the handle are each angled at 75 degrees to their long axes, the sum of their included angles would be 150 degrees. The difference between this sum and 180 degrees is 30 degrees, the resulting offset of the handle from the brush head member.
  • the present invention provides an easily adjustable angled toothbrush of a simple design which may be fabricated of two molded parts and a bifurcated pin, all of which are easily assembled.
